I still have the box for my 5G iPod sitting on some shelf somewhere, because it was just too nice to throw away. Of course, I’m a pack rat and keep worthless stuff all the time. But now I have a decent reason to keep the thing, at least if I buy a new Nano. Japanese gadget outfitter Bird Electron has a sweet little kit to convert your Nano’s box into a little portable speaker set – and as you might expect, it’s kawaii (cute) but like other battery-powered tiny speakers probably sounds like booty. Still, at 2100 yens that’s just about $20 for an iPod accessory no one else has, and you know that’s gold.
